Federal Register / Vol. 75, No. 159 / Wednesday, August 18, 2010 / Rules and Regulations
Authority for This Rulemaking
Title 49 of the United States Code
specifies the FAA’s authority to issue
rules on aviation safety. Subtitle I,
section 106, describes the authority of
the FAA Administrator. ‘‘Subtitle VII:
Aviation Programs,’’ describes in more
detail the scope of the Agency’s
authority.
We are issuing this rulemaking under
the authority described in ‘‘Subtitle VII,
Part A, Subpart III, Section 44701:
General requirements.’’ Under that
section, Congress charges the FAA with
promoting safe flight of civil aircraft in
air commerce by prescribing regulations
for practices, methods, and procedures
the Administrator finds necessary for
safety in air commerce. This regulation
is within the scope of that authority
because it addresses an unsafe condition
that is likely to exist or develop on
products identified in this rulemaking
action.
Regulatory Findings
We determined that this AD will not
have federalism implications under
Executive Order 13132. This AD will
not have a substantial direct effect on
the States, on the relationship between
the national government and the States,
or on the distribution of power and
responsibilities among the various
levels of government.
For the reasons discussed above, I
certify this AD:
1. Is not a ‘‘significant regulatory
action’’ under Executive Order 12866;
2. Is not a ‘‘significant rule’’ under the
DOT Regulatory Policies and Procedures
(44 FR 11034, February 26, 1979); and
3. Will not have a significant
economic impact, positive or negative,
on a substantial number of small entities
under the criteria of the Regulatory
Flexibility Act.
We prepared a regulatory evaluation
of the estimated costs to comply with
this AD and placed it in the AD docket.

Adoption of the Amendment
Accordingly, under the authority
delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as
follows:
■
PART 39—AIRWORTHINESS
DIRECTIVES
1. The authority citation for part 39
continues to read as follows:
■
Authority: 49 U.S.C. 106(g), 40113, 44701.
§ 39.13
[Amended]
2. The FAA amends § 39.13 by adding
the following new AD:
■
2010–17–13 Rolls-Royce plc (Formerly
Rolls-Royce Limited): Amendment 39–
16405. Docket No. FAA–2010–0521;
Directorate Identifier 2009–NE–21–AD.
Effective Date
(a) This airworthiness directive (AD)
becomes effective September 22, 2010.
Affected ADs
(b) None.
Applicability
(c) This AD applies to Rolls-Royce plc (RR)
model RB211–524C2–19 and RB211–524C2–
B–19 turbofan engines. These engines are
installed on, but not limited to, Boeing 747
series airplanes.
Reason
(d) A number of LPT casings have been
found cracked during engine shop visit.
Cracking of the LPT casing reduces the
capability of the casing to contain debris in
the event of an LPT stage 1 blade failure.
Therefore, blade failure in an engine with a
cracked LPT casing may result in release of
uncontained high-energy debris.
We are issuing this AD to detect cracks in
the low-pressure turbine (LPT) casings,
which could result in the release of
uncontained high-energy debris in the event
of a stage 1 blade failure. Uncontained highenergy debris could result in damage to the
airplane.

November 13, 2008.
Remove Parts With Cracks
(3) Remove cracked LPT casings, found
using paragraphs (e)(1) or (e)(2) of this AD,
from service before further flight.
Alternative Methods of Compliance
(AMOCs)
(f) The Manager, Engine Certification
Office, FAA, has the authority to approve
AMOCs for this AD, if requested using the
procedures found in 14 CFR 39.19.

results from reports of the retract
cylinder support fitting for the MLG
failing during gear extension and
subsequently damaging the hydraulic
system. We are issuing this AD to
prevent corrosion and damage that
could compromise the integrity of the
retract cylinder support fitting for the
MLG, which could adversely affect the
airplane’s safe landing.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to include an airworthiness
directive (AD) that would apply to
certain Model MD–90–30 airplanes.
That NPRM was published in the
50879
Federal Register on April 26, 2010 (75
FR 21528). That NPRM proposed to
require inspecting for corrosion of the
retract cylinder support fitting for the
main landing gear (MLG) and the mating
bore for the support fitting in the MLG
trunnion fitting, performing corrective
actions if necessary, and replacing
cadmium-plated retract cylinder
support bushings and bearings.
Comments
We gave the public the opportunity to
participate in developing this AD. We
received no comments on the NPRM or
on the determination of the cost to the
public.
Conclusion
We reviewed the relevant data and
determined that air safety and the
public interest require adopting the AD
as proposed.
Costs of Compliance
We estimate that this AD affects 16
airplanes of U.S. registry. The following
table provides the estimated costs for
U.S. operators to comply with this AD.

Effective Date
(a) This airworthiness directive (AD) is effective September 22,

Applicability
(c) This AD applies to McDonnell Douglas Corporation Model MD-

Boeing Service Bulletin MD90-57-016, Revision 2, dated April 28,
2006.
Subject
(d) Air Transport Association (ATA) of America Code 57: Wings.
Unsafe Condition
(e) This AD results from reports of the retract cylinder support
fitting for the main landing gear (MLG) failing during gear
extension, and subsequently damaging the hydraulic system. The
Federal Aviation Administration is issuing this AD to prevent
corrosion and damage that could compromise the integrity of the
retract cylinder support fitting for the MLG, which could adversely
affect the airplane's safe landing.
Compliance
(f) You are responsible for having the actions required by this
AD performed within the compliance times specified, unless the
actions have already been done.
Inspection and Corrective Actions
(g) Before the accumulation of 30,000 total flight hours, or
within 15,000 flight hours after the effective date of this AD,
whichever occurs later, do a general visual inspection of the
retract cylinder support fitting for the MLG and the mating bore in
the MLG trunnion fitting for corrosion, install bushings and
bearings without cadmium plating in the bore, and do all applicable
corrective actions, in accordance with Configuration 1 of the
Accomplishment Instructions of Boeing Service Bulletin MD90-57-016,
Revision 2, dated April 28, 2006. Do all applicable corrective
actions before further flight.
Note 1: For the purposes of this AD, a general visual inspection
is: ``A visual examination of an interior or exterior area,
installation, or assembly to detect obvious damage, failure, or
irregularity. This level of inspection is made from within touching
distance unless otherwise specified. A mirror may be necessary to
ensure visual access to all surfaces in the inspection area. This
level of inspection is made under normally available lighting
conditions such as daylight, hangar lighting, flashlight, or
droplight and may require removal or opening of access panels or
doors. Stands, ladders, or platforms may be required to gain
proximity to the area being checked.''
(h) Doing a general visual inspection, installing bushings and
bearings, and doing all applicable corrective actions is also
acceptable for compliance with the requirements of paragraph (g) of
this AD if done before the effective date of this AD in accordance
with the Accomplishment Instructions of Boeing Service Bulletin
MD90-57-016, Revision 1, dated October 26, 2005.
(i) Doing a general visual inspection, installing bushings and

this AD if done before the effective date of this AD in accordance
with the Accomplishment Instructions of Boeing Service Bulletin
MD90-57-016, dated September 18, 2002, provided that before the
accumulation of 30,000 total flight hours, or within 15,000 flight
hours after the effective date of this AD, whichever occurs later,
